Creating the Pistachio Kataifi Chocolate Bar is simple if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Kataifi: In a bowl, separate the kataifi pastry strands. Drizzle the melted butter over the pastry and mix well to ensure even coating.
3. Bake the Kataifi: Spread the buttered kataifi evenly in a baking dish. Bake for 20-25 minutes, or until golden brown and crisp. Remove from the oven and let it cool.
4. Make the Chocolate Filling: In a saucepan, heat the heavy cream over medium heat until it simmers. Remove from heat and add the chopped dark chocolate. Stir until completely melted and smooth. Add a pinch of salt and the vanilla extract. Mix well.
5. Assemble the Bars: Once the kataifi has cooled, spread the melted chocolate mixture evenly over the kataifi layer. Sprinkle the chopped pistachios on top of the chocolate layer.
6. Chill: Allow the chocolate to cool at room temperature for a few minutes, then place the dish in the refrigerator for about 30 minutes, or until the chocolate has set.
7. Cut into Bars: Once set, remove from the refrigerator and cut into desired bar sizes.
8. Serve: Arrange the bars on a serving platter and enjoy!
